Should I avoid hills or uneven ground? 

In the UK, patients with Peripheral Vascular Disease (PVD) do not necessarily need to avoid hills or uneven ground, but they should approach them with caution until their fitness improves. While walking on an incline increases the workload on your leg muscles and triggers claudication pain more quickly, this added resistance can actually accelerate the growth of collateral circulation if managed correctly. However, uneven ground poses a higher risk of falls and minor foot injuries, which can be dangerous for those with poor circulation. In 2026, clinical advice focuses on mastering flat ground walking before gradually introducing hills as part of a structured training plan. 

Managing PVD requires a balance between challenging your cardiovascular system and ensuring your physical safety. Hills and inclines are essentially a more intense version of flat-ground walking, requiring more oxygen and causing the ‘claudication threshold’ to be reached sooner. For some, this is an excellent way to intensify their training, but for others, it may lead to excessive fatigue or injury. This article explores the physiological impact of different terrains, the safety considerations for your feet, and the clinical triggers for progressing your walking routine in 2026. 

What We will cover in this Article 

• The impact of hills and inclines on oxygen demand. 

• Why uneven ground increases the risk of foot ulcers. 

• The role of clination training in vascular rehabilitation. 

• Safety precautions for balance and stability. 

• How to use inclines to trigger collateral circulation. 

• Choosing the right footwear for varied terrain. 

• Differentiation between muscle fatigue and ischaemic pain. 

The impact of hills on claudication 

Walking up a hill requires significantly more energy than walking on a flat surface. For someone with PVD, this means the leg muscles will demand more oxygen than the narrowed arteries can provide almost immediately. As a result, claudication pain will start much sooner and feel more intense. While this can be frustrating, it is not inherently harmful if you continue to use the stop-start method. 

Incline training 

Walking on a gentle incline is often used in supervised exercise programmes to increase the ‘ischaemic stimulus’. By forcing the muscles to work harder, you release higher levels of growth factors that encourage the development of natural bypass vessels. If you find flat walking is no longer challenging, moving to a slight hill can be a primary trigger for further circulatory improvement. 

However, you should avoid very steep hills that force you to stop every few seconds. The goal is to accumulate thirty minutes of walking, and if the terrain is too difficult, you may become exhausted before you achieve enough total training time. 

Risks of uneven ground and foot health 

While hills are a matter of intensity, uneven ground such as cobbled streets, gravel paths, or grassy fields is a matter of safety. For patients with PVD, particularly those who also have diabetes, the feet are highly vulnerable. Uneven surfaces can cause the foot to rub against the inside of a shoe, creating blisters or small cuts. 

Foot injury risk 

Because circulation is poor, a minor blister caused by walking on uneven ground can quickly turn into a non-healing arterial ulcer. Furthermore, many PVD patients have reduced sensation in their feet (neuropathy), meaning they may not feel a stone in their shoe or a twist in their ankle until significant damage has been done. For these reasons, UK clinicians generally recommend sticking to flat, well-maintained pavements or treadmills. 

Safety and stability considerations 

PVD can sometimes affect your balance, especially if you have pain in both legs or if the disease has led to muscle weakness. Walking on hills or rough terrain increases the demand on your core stability and balance. 

Balance triggers 

Visual Monitoring 

When walking on uneven ground, you must pay closer attention to where you step. If you have any dizziness or balance issues, this can lead to falls. In 2026, the use of walking poles is often recommended for PVD patients who wish to tackle more varied terrain, as they provide extra stability and reduce the load on the leg joints. 

Muscle Fatigue 

Inclines cause the muscles to tire more quickly. Fatigued muscles are less able to stabilize the ankle and knee joints, increasing the risk of trips. Always ensure you are well-rested and that your claudication pain has completely vanished before tackling a new slope. 

Differentiation: Terrain types 

Choosing the right place to walk is a key part of your treatment plan. Use the table below to decide which terrain is best for your current stage of recovery. 

Terrain Type	Benefit	Risk Level	Recommendation
Flat Pavement	Consistent, safe, easy to track	Low	Best for beginners and daily sessions
Treadmill	Controlled incline and speed	Low	Excellent for structured training
Gentle Hills	Increases vascular stimulus	Moderate	Use once flat walking feels ‘easy’
Rough Trails	Fresh air and variety	High	Avoid if you have poor foot sensation
Steep Inclines	Maximum heart effort	Moderate	Only for those with high baseline fitness

To Summarise 

You do not need to avoid hills entirely, but you should use them strategically to increase the intensity of your training once you can walk comfortably on flat ground. However, you should be very cautious with uneven ground due to the high risk of foot injuries and falls. In 2026, the clinical priority for PVD management is safety and consistency. Mastering the stop-start method on a predictable surface is the most effective way to protect your feet while improving your circulation. If you experience severe, sudden, or worsening symptoms, especially a cold, pale, or numb foot, call 999 immediately.
